beneath the lip 21 and abuts the wall 30 included between the lip 21 and the ledge 28 and, between its rearward and forward sides, the table 24 rests on the upstanding lip 29. The weight of the table overhanging the lip 29 restrains upward displacement of the table and the lip 21 and ledge 28 prevent the table from dropping into the firebox. Since the vertical distance between the lip 21 and the upper edge of the lip 29 is approximately the thickness of the rearward portion of the table, the table normally assumes a substantially horizontal position.

Fore and aft movement of the distributing' table is prevented by the lugs 3| which depend from the underside of the table 24 and iit closely adjacent the inner surface of the lip 29 when the table is in operative position and by reason of the fact that the rearward side of the table abuts the wall 30. Lateral movement of the table is pre-. vented by the vane 32 which is formed with the' ledge 28 and fits between the lugsA 3l when the table is in'position. .Provisions have been made whereby the table 24 can be conveniently placed in operative position and similarly disengaged from the distributor head-and removed when itiis desired to do so for purpose of repair, replacement or other reasons. The wall 30 and the inner surfaceof the lip 29 are curved and described on a common radius. The side of the table 24 abutting the wall 30 and the sides of the lugs 3| contacting the inner surface of the lip 29 are likewise curved and described on such common radius. This permits the table 24 to be raised about its rearward side as a pivot and to be removed from en- -gagement with the distributor head when the lugs 3| have cleared the upper edge of the lip 29. Normally such, upward movement is restrained by the overhanging weight of the table 24, so'that forv all practical purposes the table is securely and immovably engageable with the distributor head i9. The height to which the table must be raised before it can beV disengaged from the head is determined' by the height of the'lugs 3|. The higher thelugs 3`I are the higher the table must be raised in order that the For practical purposes the distance to which the table must be raised before it can be disengaged is suchfasto eliminate the possibility of accidental disengagement. It will-'be obvious that neither the-entire contacting surfaces nor all of them neednecessarily be curved to effect the above result, it having been shown in this manner in the drawings for purposes of illustrationl and such modifications as effect the same result with fewer curved surfaces or with partially curved surfaces come within the purview of my invention.`

Figures 4, 5 and 6 show a slightly modified form of the invention, differing fromthe preferred form in that downward movement of the table 4 about the support ledge and lip 4 l, 42 is prevented bythe spaced tongues 43 and 44 ,which depend from the underside of the table and extend rearwardly `beneath the distributor head 45. The tongues 43 and 44 are spaced apart a distance suicient to permit the ledge 4I to pass therebetween when placing the table in position.

From the foregoing it will 'be understood `that the rearV section of the distributing mechanism need not be made in the form of a chambered distributor head but may constitute the rear section of a two section distributor plate over which fuel ,may be propelled by pressure fluid blasts disrearward charged from a point rearward thereof or in any other operative position.
